UNDERCLEARER ROLL Filed Aug. 29. 1930 Patented Aug. 30, 1932 UNITED STATES PATENT OFFICE NOAH E. LUCAS, OF NORWICH, CONNECTICUT UNDERCLEABER ROLL Application filed August 29,1930. Serial N0. 478,633.

1e type that shall be particularly durable, light in structure, one that shall maintain its form under the conditions to which it may be subjected, and also one from which the mass col lected thereon may bereadily removed.

One form of an underclearer roll embodying my invention, and in the construction and use of which, the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawing, in which Figure 1 is a side view of my improved underclearer roll.

Figure 2 is a view in central lengthwise section through the same.

Figure 3 is a View similar to Figure 2 but 25 illustrating a little different form of the roll.

In the accompanying drawing the numeral 4 indicates the body of the roll that is of tubular form, the walls being comparatively thin and merely of a thickness to afford the requi- 30 site strength for the roll. While the roll may be composed of any suitable material, paper is preferred by me. This will be compressed to the required extent to afford the necessary rigidity.

The machinery, as spinning frames and the like, in connection with which these rolls are used, are subject to extremely moist conditions in the rooms in which the machines are located and this condition seriously afi-ects the rolls which are warped and distorted under such conditions. In order to avoid the undesirable effects of sad conditions, I create a chamber 5 within the body of the roll by the insertion of a plug 6 in the opposite ends thereof. The chamber 5 is thus completely sealed and this sealed chamber prevents the roll from warping and efiects the maintenance of the original shape and form of the roll.

In the preferred form of the structure the plugs 6 are composed of wood and a head? is integrally formed on each of the plugs. The

plugs are preferably secured in place as by glue or any other suitable adhesive and the head 7 not only aflords a seat for the plug to limit its inward movement, but said head also assists in the sealing of the chamber 5.

A pin 8 preferably having a flange 9 is driven into each of the plugs 6, the outer ends of said pins comprising the bearings for the rolls.

A groove 10 is preferably formed eXtend- 7 ing spirally about the roll, said groove having a shoulder 11 on one side that acts as a catcher to collect the fluffy matter or lint,

and the thread ends, said groove tapering out gradually from said shoulder to the opposite side thereof. I have found that a roll constructed of paper, as shown herein, very satisfactorily effects the operation of catching loose ends and other material, and when the groove is formed in such paper roll, a very effectlve underclearer roll is produced.

The device shown in Figure 3 1s substantially as hereinabove described, the difference. '2'

being that the plug 6 does not have the head integrally formed thereon, such head, in this structure, being in the form of a washer 12 that may be composed of any suitable material, as any desired composition of matter. v In this form of the device the pin 13 is provided with a screw thread by means of which it is secured in the plug 6. The head 7 and the washer 12 in both forms of the device are made slightly smaller in diameter than,

the body 4 of the roll in order that the material which accumulates on the roll may be readily slid off from the end of the roll, the spiral groove particularly facilitating this operation. The heads being smaller than the rolls, no shoulders are presented to prevent tion may be carried out by other means and applied to uses other than those above set out.

I claim:

5 1. An underclearer roll comprising a. body com osed of paper and formed with an opening rom endto end'thereofi'aiplugcompcmd of wood secured by-"an adhesive in *the ends of the hole through said body to seal the w chamber therein, and ta journalsecured .to

and projecting from said plug.

2. An underclearer roll comprisingea low body composed of paper with a shoulder groove spirally formed on .therouterisurfane 15 of the body, said body being in the form of a tube, a plug 'secured byaniadhesive inthe :enll of-aaid tube to sealthe-"chamber therein, 'aih'sldam=saidplugsmaller in 'di-ameterithan said mrbe =but abutting the ends thereof; and

a journal secured to and projecting "from said-plug. e
